When going to meet Rosa at the City Library, in the first room on the left after the objective begins, you can find a desk hidden behind a shelf. On the desk is a TV displaying an image of a detective badge, and connected to it is an Xbox 360 with a custom skin based on Condemned: Criminal Origins. Turning off the TV will unlock the Xbox Achievement "Silver Detective Badge". It's unknown if this skin mock-up was actually intended to be produced and released as a real product.

The achievements in the game only add up to 970 points, whereas most games have a total of 1000. Apparently extra content was planned as DLC, including additional achievements, but it was never released.
